Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new method for suppressing corrosion for a reinforcing bar embedded in concrete of an existing reinforced concrete structure exposed to salt water such as sea water or a snow melting agent, which has a relatively easy construction method, is excellent in chemical safety and uses an inexpensive material.SOLUTION: There is provided the method for suppressing corrosion of the reinforcing bar embedded in the existing reinforced concrete. At least one part of the concrete on the surface of the existing reinforced concrete in which salt damage occurred or may occur is chipped. At least one part of the chipped part is filled with mortar containing strongly basic anion exchange resin to repair a cross section.
